Description

Technical Field

[0001] This application belongs to the field of chipper technology, and particularly relates to a drum chipper with a receiving cylinder mounting structure. Background Technology

[0002] Drum chippers are traditional products that can cut logs and small-diameter timber into high-quality industrial wood chips of uniform length, smooth cut, and even thickness. They can also cut branches and boards. The wood is fed into the chipper through the inlet. When the wood comes into contact with the cutting blades, it is chipped by the high-speed rotation of the cutting disc. The cutting mechanism is a rotating drum with several flying knives mounted on it. As the flying knives rotate, they process the wood into chips. The outer edge of the drum has multiple square through holes. The qualified chips fall through the mesh screen and are discharged at the bottom. Larger chips are further chopped inside the machine.

[0003] Patent CN222155941U discloses a drum chipper, including a chipper body and a discharge structure. The discharge structure includes: a mounting base, a discharge pipe, a receiving hopper, a connecting base, and a dust collection structure. The mounting base is connected to the discharge port of the chipper body; the upper end of the discharge pipe is connected to the mounting base; the receiving hopper is located below the discharge pipe; the connecting base is used to connect the lower end of the discharge pipe to the receiving hopper; the mounting base, discharge pipe, connecting base, and receiving hopper are interconnected to form a discharge channel; the dust collection structure is connected to the mounting base or the discharge channel to collect wood dust in the discharge channel.

[0004] The aforementioned patent connects to the receiving bucket by setting up a mounting base and a discharge pipe. The mounting base is installed by fasteners through threaded holes on the machine body. Although this can achieve a fixing effect, directly opening the holes on the chipper body can easily lead to thread wear and loss of fixation, so improvements are needed. Utility Model Content

[0022] The elongated protrusion is internally provided with a third through hole with the same diameter as the second through hole;

[0023] The elongated cap is arranged on the elongated protrusion, and a fourth through hole is formed in the surface of the elongated cap and communicates with the third through hole;

[0024] The diameter of the fourth through hole is the same as that of the rod portion, the diameters of the third through hole and the second through hole are greater than that of the rod portion, and a guide groove is formed between the third through hole and the second through hole.

[0025] The elongated protrusion is mounted on the elongated plate, and is internally provided with a third through hole with the same diameter as the second through hole, the third through hole is not only aligned with the second through hole, but also forms a longer channel to provide additional guidance and support for the fastener. The elongated cap is arranged on the elongated protrusion, and a fourth through hole is formed in the surface of the elongated cap and communicates with the third through hole, the diameter of the fourth through hole is the same as that of the rod portion of the fastener, so that the fastener can smoothly pass through. And the elongated cap provides a larger contact surface for the installation of the fastener, improves the fastening effect, and also protects the elongated protrusion from damage when the end is tightened.

[0026] The third through hole, the second through hole and the guide groove formed therebetween collectively provide a guide path for the fastener, not only ensuring that the fastener can accurately pass through all the holes and cooperate with the threaded hole, but also providing additional support to prevent the fastener from bending or deviating during installation. The fourth through hole on the elongated cap closely cooperates with the rod portion of the fastener, plays a limiting role, prevents the fastener from deviating during installation, and ensures the stability of the installation. In addition, the diameters of the third through hole and the second through hole are greater than that of the rod portion, so that the inner wall and the threads on the rod portion are prevented from contacting, thereby avoiding wear and tear.

[0027] Further, the guide groove is provided with a fixed ring plate, the fixed ring plate is arranged on the outer wall of the rod portion, and the fixed ring plate and the guide groove have a certain gap and can move in the guide groove with the movement of the rod portion.
